Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko gaming machine in which a grand prize opening opens and closes when a game ball enters a starting opening.

[Conventional technology]

Pachinko gaming machines generally have multiple winning holes on the game board surface, and when a player drives the game ball he or she has purchased along the game board and the game ball enters the winning hole, a certain number of prize balls will be awarded. It is about to be paid out. In such pachinko gaming machines, all a player has to do is to put purchased game balls into a supply tray and operate a ball-striking handle to fire the game balls, so the game tends to be monotonous.

Therefore, in order to vary the game content, a big prize opening is provided on the game board surface, and the game ball is inserted into the second type starting opening A pachinko game machine has been devised in which when a player wins a prize, the grand prize opening opens and closes a predetermined number of times.

In such a pachinko game machine, when a game ball enters the second type starting hole, the big winning hole opens and closes once or twice, and during this time, the game ball enters a special hole provided inside the big winning hole.
If you win a prize in the winning hole, you will also have the right to continue opening and closing the big winning hole 18 times in a row. And this 18
If the game ball enters the V winning hole in the big winning hole during the continuous operation of the round, the right to continue opening and closing the big winning hole for that round even in the middle of the 18th round will be lost and the right to continue opening and closing the big winning hole for that round will be renewed. The right is generated and the next 18 consecutive opening/closing operations are performed. Also, 18 times i! If the game ball does not enter the winning hole during the continuous movement, after 18 consecutive movements in that round are completed, or the number of game balls entered into the big winning hole reaches 10. When the opening/closing operation of the big prize opening ends. Incidentally, the 18 consecutive opening/closing operations can be repeated for a total of 8 rounds, and after 8 rounds are repeated, the original initial state is returned.

[Problem to be solved by the invention]

By the way, in conventional pachinko gaming machines, the probability of a ball entering a specific opening was adjusted by devising the mechanical structure such as the position and size of the specific opening. It was not easy for pachinko machine manufacturers to adjust the ball launch. In addition, in gaming parlors, the only way to adjust the probability of a ball entering a specific opening was by adjusting the nails, so at a gaming parlor, the probability of a ball entering a specific opening could be adjusted to increase the ball output from a pachinko machine. It was almost impossible to adjust.

The present invention has been made based on the above-mentioned circumstances, and provides a pachinko game machine that can easily adjust the probability of a ball entering a specific hole provided inside a big winning hole even in a game hall. The purpose is to

[Means to solve the problem]

To achieve the above object, the present invention has a big winning hole and a starting hole on the game board surface, and when a game ball enters the starting hole, the big winning hole opens and closes a predetermined number of times. In a pachinko game machine that can continue the opening and closing operation of the big prize opening when a game ball enters a specific opening provided inside the big winning opening during an opening/closing drive means for setting the opening state to an open state or a closed state in which a game ball is difficult to enter; and at least when the big prize opening is performing an opening/closing operation, the opening/closing driving means is driven to bring the specific opening into an open state and a closed state. It is provided with a control means for controlling the operating state to be alternately repeated, and a setting means for presetting the time period for at least one of the open state and the closed state of the specific mouth controlled by the control means. .

[Effect]

According to the above-mentioned means, when the game ball enters the second type starting hole and the grand prize opening is opened and closed a predetermined number of times, the control means drives the opening/closing driving means to open the specific opening. The operating state is controlled such that the operating state alternately repeats the closed state and the closed state. Here, the time period for at least one of the open state and closed state of the specific mouth controlled by the control means can be set in advance by the setting means. For example, when it is desired to increase the amount of self-balls, the setting means is used to set a longer time for the specific mouth to be open and a shorter time for the specific mouth to be in the closed state. This makes it easier for the game ball to enter the specific hole when the big winning hole is opening and closing, making it easier for the right to continue opening and closing the big winning hole, increasing the amount of own balls. be able to. Further, when it is desired to reduce the amount of self-balls, the setting means is used to set a short time for the specific mouth to be in the open state and a long time for the specific mouth to be in the closed state. As a result, even if the big winning hole opens and closes, it becomes difficult for the game ball to enter the specific hole, so it becomes difficult to generate the right to continue opening and closing the big winning hole, and it is possible to reduce the amount of own balls. can.

In addition, it may be possible to set the specific mouth to be open for a longer period of time in the morning and closed for a longer period of time in the afternoon on -day, so that the number of self-balls is large in the morning, In the afternoon, the amount of pitches he throws will decrease. Furthermore, a timer or the like may be used to set the time period during which the specific mouth is open and closed at regular intervals.

This makes it possible to adjust the ball hitting rate at regular intervals.

a first judgment section that issues a signal to the gate GI when the count' value reaches a predetermined constant value, 56 a second counting section that counts the signal from the lO count switch S, 57 a second This is a second determining section that issues a signal to the gate G1 when the count value of the counting section reaches a predetermined constant value.

The operation of this embodiment will be described below with reference to the time chart shown in FIG.

First, it is assumed that the setting section 52a of the pachinko game machine according to this embodiment has been set to the first setting state by an attendant of the game parlor or the like. When the power is turned on, the control circuit of the big prize opening composed of CPtJ initializes, and then the setting section 52a
The setting state of the pachinko game machine is read and the pachinko game machine is set to a playable state. Now, suppose that the game ball shot by the player wins, for example, the second type starting opening 4b in which the big winning opening 2 opens and closes twice. Then, the N detector St detects this and sends a signal to the movable blade control circuit 50.
0 excites the first solenoid 12 via the first drive unit 51, thereby causing the movable blades 11a and 11b to rotate twice, and the big prize opening 2 to open and close twice. Further, the movable vane control circuit 50 issues a signal to the opening/closing control circuit 52. Upon receiving this signal, the opening/closing control circuit 52 operates the second solenoid 22 via the second drive section, and puts the opening/closing lid 20 into an operating state that alternately repeats a storage state and an extrusion state.

As a result, during the opening/closing operation of the big winning opening 2, ■ winning opening 13
The opening may be open or closed. Then, when the grand prize opening 2 is in the open state, if the game ball fired by the player enters the grand prize opening 2, the game ball will be sent to the three winning holes 13 arranged at the bottom of the big winning opening 2.・
Win either 14a or 14b. Prize opening 14a・
When winning 14b, a predetermined game ball is simply ejected as a prize ball, but when the game ball enters the open V winning hole 13, the detector S detects this. The signal is sent to the movable vane control circuit 50 and the opening/closing lid control circuit 52. Then, the round display 3 displays rlJ to indicate that the right to continue the opening/closing operation of the grand prize opening 2 has been generated.

When the movable vane control circuit 50 receives the output signal from the V detector S4, it excites the first solenoid 12 and controls the movable vanes 11a.
llb is controlled to perform a continuous rotation operation, and thereby the big prize opening 2 shifts to a continuous opening/closing operation. The first counting unit 54 receives a signal from the movable blade control circuit 50 and counts the number of continuous rotation operations of the movable blades 11a and 11b, that is, the number of continuous opening and closing operations of the big prize opening 2. When the number of consecutive opening and closing operations of the big prize opening 2 reaches a predetermined 18 times, the first judgment section 55 issues a signal to the gate CI. Also, big prize opening 2
A 10 count switch S detects the winning number of game balls that entered the big prize opening 2 during the continuous opening/closing operation, and sends its output signal to the second counting section 56. The second counting section 56 counts the output signal.

When the number of winning game balls in the grand prize opening 2 reaches 10, the second
The determining unit 57 issues a signal to the gate GI. Gate G r
is an OR gate, so the first judgment unit 55 or the second
Upon receiving the signal from the determination unit 57, the movable blade control circuit 50
send a signal to. When the movable vane control circuit 50 receives the signal from the gate GI, it stops the rotating operation of the movable vane 11allb, and also controls the first counting section 54 and the second counting section 56.
Reset. In other words, the rotating operation of the movable wing m1la-11b, that is, the continuous opening and closing operation of the big winning hole 2, will be repeated 18 times if the game ball does not enter the V winning hole 13 during the 18 consecutive operations. Repeat or big prize opening 2
The game ends when 10 game balls are won.

FIG. 5 is a time chart showing the opening/closing operation of the big prize opening. Fig. 5(a) shows that the game ball is opened and closed once, and the movable blade rotates only once, that is, the big prize opening 2 is opened and closed once.
Performs opening/closing operations. FIG. 5(b) shows a case where a game ball enters the second type opening/closing starting opening, and similarly, the big winning opening 2 performs opening/closing operations twice. FIG. 5(C) shows that when the game ball enters any of the second type starting openings 4a, 4b, and 4C and the grand prize opening 2 becomes open, the game ball enters the grand prize opening 2. And, what's more, the game ball is in the open state.■ Winning hole 1
This shows the case where the prize is won in 3rd prize. In other words, when a game ball enters the opened grand prize opening 2 and the game ball enters the winning opening 13 provided at the bottom of the grand prize opening 2, the detector S4 transmits the detection signal to the movable blade control circuit. 50 and the opening/closing lid control circuit 52, the right to continue the opening/closing operation of the big prize opening 2 is generated, and the round display 3 displays rlJ. And, the big prize opening 2 will repeat the opening and closing operation 18 times in a row,
Or until 10 game balls enter the grand prize opening 2,
If the game ball does not enter the V winning hole 13 in the big winning hole 2, the continuous operation ends and returns to the initial state. However, during this time, when the game ball that entered the big winning hole 2 enters the V winning hole 13 again, and the detector S sends a signal to the movable blade control circuit 50, for example, as shown in FIG. 5(C). Big prize opening 2 to 1
When the game ball enters the V winning hole 13 of the big winning hole 2 while performing the opening/closing operation for the 44th time, the right to continue the opening/closing operation of the aforementioned big winning hole 2 at that point A is extinguished. . Then, the right to continue the opening/closing operation of the big prize opening 2 is newly generated from time A, and the round indicator 3 displays "2". Then, until the grand prize opening 2 repeats the opening/closing operation 18 times, or until 10 game balls enter the grand prize opening 2, as described above, the game ball enters the V winning opening 1.
3, the right to continue opening and closing the grand prize opening 2 is renewed, and the above-mentioned operation is repeated thereafter. In addition, when the right to continue the opening/closing operation of the big prize opening 2 occurs continuously, when the 8th right is extinguished, that is, after 8 rounds of 18 consecutive opening/closing operations, the initial Return to state.

Here, the setting section 52a of this pachinko game machine is set to the first setting state, and is opened and closed in the morning! ! Since the time in the storage state of 20 is long and the time in the extrusion state is short, it is easy for the game ball to enter the V winning hole 13, and the right to continue the opening and closing operation of the big winning hole 2 is likely to occur, but in the afternoon Since the time in the stored state is short and the time in the extruded state is long, the game ball is in the V winning slot 1.
3 becomes difficult, and it becomes difficult to obtain the right to continue opening and closing the Omoto prize opening 2. That is, the setting section 52
When a is set to the first setting state, the pachinko game machine produces a large amount of small balls in the morning, but decreases in the afternoon.

Next, when you want to increase the amount of small balls in your pachinko machine,
For example, when adjusting the output Fi after the game hall is closed, the second setting state is set by a dip switch (not shown) of the setting section 521. As a result, pachinko machines - during the day,
The time in the stored state of the opening/closing lid 20 is longer than the time in the pushed out state, and the game ball is in a state where it is easy to enter the V winning hole 13, so the right to continue the opening/closing operation of the big winning hole 2 is likely to occur. Become. Therefore, the amount of globules increases.

Further, when it is desired to reduce the amount of small balls in the pachinko game machine, the third setting state is similarly set using a dip switch (not shown) of the setting section 52a. As a result, the pachinko game machine - During the day, the time in which the opening/closing lid 20 is in the retracted state is shorter than the time in the pushed-out state, making it difficult for game balls to enter the winning hole 13; It becomes difficult to obtain the right to continue the opening/closing operation of step 2. Therefore, the amount of globules is reduced.

In this way, according to this embodiment, the opening/closing lid 2 of the winning opening 13 is controlled by the setting section 52a provided on the back surface of the game board l.
By controlling the time of the open state and closed state of 0, it is possible to adjust the probability of a ball entering the winning hole 13, so even in a game hall, the probability of a ball entering the V winning hole 13 can be adjusted easily. You can adjust your pitch accordingly.

In the above embodiment, a case has been described in which the setting section 52a has three setting states, but there may be two setting states, or four or more setting states.

In addition, in the above embodiment, the setting state is changed between morning and afternoon using the dip switch in the setting section. Program number 1' (2 may be used) to change the state and the time of the closed state.

Further, in the above embodiment, a case has been described in which a solenoid is used to drive the opening/closing lid, but the opening/closing lid may be driven using a servo motor or the like instead of a solenoid or an id.

Further, in the above embodiment, a case has been described in which the setting section is provided on the back side of the game board, but the setting section may be placed in a central control device that centrally manages the pachinko gaming machines in the gaming parlor.

In addition, in the above-mentioned embodiment, the case where the opening/closing lid was used as means for preventing game balls from entering the prize opening was explained; however, the present invention is not limited to this.
For example, this can be done by placing an opening/closing door on the top of the V-winning slot, or by tilting both or one of the partition plates of the winning slot inward, and closing the opening of the winning slot. good.

In the above embodiment, as the V winning opening is closed,
Although we have explained the case where the game ball cannot enter the ball, this closed state is not limited to the case where the game ball cannot enter the ball.
Although it is possible for a game ball to enter, the state may be such that it is more difficult for a game ball to enter than in the open state.

Although the above describes a pachinko game machine with a type 2 starting lottery, the present invention is not limited thereto, and it is necessary to distribute game balls at a certain probability after winning a prize, such as a pachinko gaming machine with a type 1 starting lottery. It can also be used in other pachinko gaming machines.

〔Effect of the invention〕

As explained above, according to the present invention, the probability of a game ball entering a specific opening is adjusted by changing the time for which the specific opening is open or closed. By adjusting the ball entry probability, it is possible to provide a pachinko game machine that can easily perform ratio adjustment.
